Dude, could you turn your screen down? Trying to carry a conversation over here.
The Dollar Guy No I can not.
Just lower the refresh rate
@@spark198rus
Or increase it beyond 20khz, good luck.
Should paint the dark side with vantablack. OLED level contrast!
Good idea!
Good idea indeed!
That would be too much since theres only 2 colors
@@probreyene9595 he's not saying to add a color, just replace the current black with vantablack.
Yea but i though contrast is already great
I love the sound it makes. It's unlike anything else.
I wander if you can drive it such that it produces a recognisable tune.
keoni29 A truly cancerous sound.
DutchPhlogiston Doom theme music has my vote.
It sounds like thousands of butterflies
keoni29 it sounds like a rattle snake
"In Every Pixel"... Except for the ones that are stuck
I hate stuck pixels :D
just recently noticed one in the middle of my laptop screen :D
drives me mad..... always purpleish green little fucker
The pixels in your laptop and the pixels in this screen are different.
***** No. Why?
Flipdot pixels are electro-mechanical so they actually get stuck much more often than purely electronic (OLED and SED) or electro-chemical (LCD and Plasma) ones... DLP is also electro-mechanical just like Flipdot however because DLP is built as a microchip and is protected from the air in a vacuum, DLP is also much more reliable than Flipdot. Flipdot requires a lot of power to drive each mechanism because they are huge motorized things and they are exposed to air.
666th like.
A perfect example of RUclips video compression gone crazy.
I think its the screens limit that makes the blocks.
@@LordGryllwotth or is it all the power between the pixels? 🤔🤔
It's all video compression really. You can't have real images as frames if you don't want a 150GB/min file
@@paskky913photos are 15mb~ on highest quality for my s21 i think your right lol
It does the "static snow" transition every time because i think it cannot toggle all pixels at the same time: back EMF from coils would be too huge to handle. So it toggles just 1/10th at a time, in pseudorandom snow.
If it is like other displays, it can only flip one column at a time due to the limits of multiplexing and every other row to keep neighboring rows from interfering with each other. Also it can only do that in one direction, so it has to go through that process once to turn pixels on and again to turn them off
complety fine turns all flipboard black to white one at time very fast. and you see there multiple invidual boxes and they synced starting from top corned
that would be easy to mitigate
The back EMF would be solved with a simple diode (flyback).
However you may be onto something with there being a limitation in how quickly all the pixels can be changed.
Then again given how large the pixels are, it's not going to be too much more demanding than other large screens. I guess if there is a limitation it is overcomable but they didn't go down that path for this particular setup.
"One tenthTH"? That doesn't make sense.
Display replacement will be covered under warranty only if there are 4 or more stuck or dead pixels in an area the size of a US Quarter Dollar or smaller.
So they made the pixels all the size of a quarter...
hahahahah
lmao
Pretty cool how far they managed to push the technology. Even for 6 years ago.
people were using blades of grass 6 years ago to propel cardboard boxes

4 years ago I was diagnosed with autism.
An alternate reality where this was invented before crt
Nop, it needs a ton of good digital timing to work
There is no sound? Make sure you check your room for snakes before commenting.
There was such a story, written by Bruce Sterling and William Gibson. It's called The Difference Engine. The computer age arrives a century early. In the novel, there are theaters that use these screens. The people who program the movies are called "clackers". It's a favorite. I've wanted to see a film adaptation for a very long time. Now, it can be done, but Hollywood is too busy remaking every possible movie that already exists.
fairly sure the basic premise of this kind of display is quite, quite old.
Though perhaps the driving electronics to allow it to function decently are not.

So does crt
But can it play Bad Apple?
ObiTrev yes
Yea ruclips.net/video/ko0z3SfXpm8/видео.html
Wow Bad apple
This comment is legend
You can even hear how loud the flipdots are when processing every pixel at once.
Dang, The refresh rate is very good for something mechanical like that
Actually the refresh rate is super low, the frame rate is super high, refresh is the whole screen if it were flashing on and off. Frame rate is between each pixel, and since not every pixel is changing with every frame, it can charmed really fast
@@braydenhancock3907 🤓🤓🤓🤓
Would be cool to see a demo where the music is generated by the screen itself.
that would be awesome, like reverse oscilloscope music where instead of the visuals being generated by the music being made a certain way the music is generated by the visuals being made a certain way
@@orangejuliaa What about both ways at one? Image would be constructed to generate sound that draws the same image on oscilloscope :)
The very first thing I thought of after seeing those little flip dots was, "I wonder if someone has made a display out of these before". Of course they did...
I see dead pixels :P
Flipdot isn't the most stable thing. ¯\_(ツ)_/¯
resting!
DelphiTheDolphin Dw, just give 'em a spin, they will start up again
They need to get a refund. Hope its under warranty.
What a twist!
Thanks M. Night Shamalan!
Tohou Fans would love to animate their video on this Flip-Dot Display.
All jokes aside, this is the retrofuture stuff that I like. Just imagine analog stuff being the real future instead of the real AR/VR stuff.
Not hating the AR/VR stuff, but making a modern working analog stuff would be amazing while we can touch grass too.
I kind of agree, but i just want to point out that this display is very much digital. More digital than a typical led backlit lcd display.
Flip dots would be an effective solution to minimize energy consumption on jumbotron and ads space billboard with only showing slide shows of pictures not videos. Because you can cut the power but maintaining the portrait.
@aaaaa not literally on the spot replace them directly... Kinda like when a part of it is broken or damaged... Then that's the time to replace it and all other parts could be to use in other else though like scavenging parts for other damaged jumbotron
Not really sure about how long it could last exposed to the elements but ePaper would probably be even better. Since it is just moving pigment around and you only need to use energy to change the pixel state. They also have colored variants, so at least some more variety. Also less prone to getting stuck and way smaller minimum pixel sizes.
@@jansustar4565 that nice idea too the problem is, There is no company who make that huge epaper
Why not just using those rotating triangular prism thing then ?
"Pictures not videos"? That doesn't make sense. Are you sure you don't need some sort of punctuation in there? Maybe look into that so it can make sense.
wonder how much electric it use to drive all those 74088 pixel/dots
Flip dot displays typically only consume power when each individual dot is flipped. From what I can find online, each dot typically uses somewhere between 1 and 2.5 watts of electricity for 1 to 2 milliseconds each time the dot is flipped.
At that rate, if you wanted to flip every dot just one time per hour, this 74,088 dot display would consume between 0.074 and 0.370 kilowatt hours of electricity. On the other hand, if you wanted to flip every dot once every second, this 74,088 dot display would consume between 266 and 1332 kilowatt hours of electricity.
As you see, the power consumption can be considered extremely little on average if you only update all the dots on the sign once a year or could be considered extremely high on average if you update all the dots on the sign multiple times per second. Power consumption is determined by the way you use it.
In this application, I think the power consumption is probably quite high.
If it take 2 mJ of energy to flip a disc, or 2 mW at 1 Hz, then it's only 150 W for the whole display.
Jet Li electric doesn't exist
It's multiplexed in order to not cause high power spikes, it means pixels are flipped one after the other, you can see it when the screen goes black to white
They showed it displaying white noise. that must've drawn A LOT of energy
That's the highest low resolution text I've ever seen very impressive
once there's a power outage or something happens, the screen will probably just, stop moving, so its stuck on the frame it was before
would be a cool concept for an apocalypses game
That's the same for eink displays
I remember going to Kyiv in the summer of 2022. All ads on the streets and the metro were stuck in February. Truly a time capsule.
@@anonymoususer8517 these work by the same optical principle, just on a larger scale
@@anonymoususer8517they will fade after a little while, depends on the screen how long it's gonna take
i guess no matter what, we can never escape dead pixels
Dude, video compression is totally, utterly, literally loving this to death.
"How loud is your TV man?"
"Stupid loud."
This is an incredible display, strange choice to advertise a video messaging app but I'm glad they did
Now, this is what I think of the future. It’s more mechanical than neon lights, glowing bits or screens and such.
They had this amazing display, and didn't play bad apple on it... What a shame
dude that transition from black to white at 0:47 is my favourite part, satisfying to watch and satisfying sound
Can this wall be hooked up to my Linux terminal output? That'd be awesome.
There's enough pixels. Terminal output can be as low as 320x200 if you use CGA resolution. That's still enough for 40x25 characters, same as the C64 for example. This display looks like it has more then 320 pixels across so it could easily handle it. Here's a vid of one displaying text. ruclips.net/video/7oSH-aZKyU8/видео.html It just happened to be in my reccommended next to this video.
sure. get a 15 pin to rca converter, and use an arduino to drive the display. tho youd be stuck at tv resolution at best.
Yes, but screen would be huge
Also you can try create your own with smaller dots
cat /dev/random
it's only 1-bit color depth but still
Sounds like a bunch of maracas.
It's certainly impressive, but I don't see the point, there are solutions much better and probably cheaper to build and maintain.
I think it's an interesting invention. Flip-Disc displays really stand out as a display technology and it shows the nature and evolution of displays. It uses the same exact mechanics no matter how limited it may be. All display technologies have a pixel resolution, we have not really advanced further than this idea, we only increased resolution and colors. Unlike other displays, Flip-Disc systems don't really hurt your eyes like conventional displays, it does not produce light.
They might not hurt your eyes, but they do hurt your hears ; )
But really, they don't have much to offer and I don't get why they were used here other than for being different. They are great at strong sunlight, but this installation is indoors. They don't use power when the display is not updated, but they constantly change the contents.
There are several display technologies which does not produce light. E-ink is an obvious one, but LCDs does have to produce light either, you can simply have a mirror behind it instead of a back light. (Gameboy Advance is a great example for a color display like this.) Not all displays use pixels either, e.g. 7 segment displays, nixie tubes and spit-flap displays. Black and white CRTs don't have a horizontal resolution either.
I have never heard of E-ink before. I don't know how LCDs work exactly so I don't know what you mean by simply adding a mirror to the back. Maybe one day we will move on from the current display technologies and we can simply manipulate light around us to produce visuals. I was watching this video one day and it blew my mind, the idea that when one projects colors, black is also projected: ruclips.net/video/p-OCfiglZRQ/видео.html
Thanks for sharing that information, Its nice to learn something new.
Big Sport Screens, Period.
They’re great at places where you need to wait for your number to be called. No need for speakers; everyone in the vicinity will look.
Airports
Government transactions
Train stations
Elections (every click is satisfying)
Just an opinion.
Hmm, I've already seen lower-res versions of these that were in use outside at an arena some 15 or 20 years ago, that had already been _removed_ for a while by now, in favor of better technology. And yeah, it was interesting to hear it switch dots. The pixels on that machine were about 2 inches wide, and every time some of them changed, you'd hear a big multiclick "CLACK" sound, sort of like synchronized military marching!
Alright touhou fans you know what we need to play on this
Only 1/10 000 dead pixels is pretty awesome for this digital-mechanical display. Is it a mikeselectricstuff thing?
I am curious about the power consumption during video playing compare to other display technology.
I suppose this display till good for displaying constant information for longer period rather than fast changing information. But no doubt funny to see a video on flip display. :)
UNLIMITED POWAAAH
This video has the best sound quality ever
What is that maddening sound, like strong wind, at the end of the video. Please don’t tell me it’s the display (fail).
Ain't no way they made a huge display that can only show black and white and didn't even play Bad Apple on it
Can this be used as a subwoofer
I wonder what it would look like to use subframe temporal dithering to spread out the timing of the dots changing so it doesn't make that throbbing chugging noise for each frame.
That's cool and all but can it play doom?
Damn, I need some of those displays...
That's just SICK (in a good way!)
We've come full circle! Modern people are fascinated by 1980's B&W TV!
ok now we gotta see Bad Apple on this thing
I came to the comments to say exactly this lol
What was going on at the end it sounded like someone was revving up some car engine
Now someone needs to play Bad Apple on it
Thank you youtube compression, very cool
This is something I would like to see in a retro futurism movie/game like Alien.
que es oovoo?
Wondering how loud it will be if it does support 540fps
Now, is there a practical use for this?
What camera is this? Sounds weird
What happens if you make it switch quickly between all white and all black? [harmonious bass buzzing]
Much next-gen. Very iteractions. Wow
How much is the cost of this.
Anyone here know the advantages this technology against led display? How much does cost per sq feet? Does it cheaper than led? Or it just for aesthetic purpose?
2 years late but, flipdot displays have advantages such as low power consumption, high visibility, longevity, and a unique retro aesthetic. However, they also have limitations, including limited color options, complex maintenance, and a potentially higher upfront cost compared to LED displays
so...low res noisy monochromatic tv?....but why though?
whats the loud sound towards the end?
0:58 haven't seen black and white dithering in a very long time.
So whats the advantage of this tech?
Its really cool for sure, but is there any actual use for this?
for much smaller displays, flip dots are great because they don't require power when they aren't being flipped. They're also very easy to read. Something of this scale is purely for entertainment, you'd be better off using LED's.
Gazelle Samyueru Maybe displaying time and temperature or a menu. Readable in full sun and doesn't need to be updated a lot (time needs to be updated once in a minute, and not all pixels).
Isn't ooVoo a facetimey thing
Why werent more people watching this, this is so cool
That is not much considering even resolution like 640x480 has over 300 000 pixels
mmh. But we went through most of the 80's with a sizeable portion of computers using 320x240 or lower resolutions.
320x240 is 76,800 pixels, so that gives a good sense of what kind of display this is equivalent to.
If you have a PC by the way it's likely still booting in 320x200 even to this day.
I wonder what the refresh rate here is
What's with the sound effects?
OOVOO what's this?
1:22 What the flip is wrong with the sound ❓
i dont understand why this is saying next gen when it looks like colorless pixel art, what is going on here?
Harnessing the power between the pixels
Anyone else just waiting for it to play Bad Apple? 😂😅
After I saw the stuck pixels I couldn't unsee them
What's with the audio at 1:19 and on?
What is this? 1990? 74000 pixels is less than 240p...
but does it run Crysis
ooVoo ??
0:38 Is that lady on the bottom left trying to interview the screen?
Where's the Bad Apple?
you guys i think they are harnessing the power between the pixels
I can hear a picture.
But can it play bad apple?
Is it though?
It has dead pixels, can i return it?
Jacob Smith im not an mechanic... *throws it out the window*
Missed opportunity to call it the ooVoo Javer
why is buddy like an inch away
whos your favourite oovoo driver
the ONLY positive in this i can see, is the repair/replaceability of broken down "pixels" & the lower energy requirements, compared to other displays, but apart from that, no reason to want to have a slow, loud & rough pixeled picture these days!
"Pixels" in quotes? Why: are they not _actual_ to you?
0:55 was that rebeca black's friday???
These will be everywhere.....
+GAME OVER "WE HAVE EVERY PIXEL COVERED" no it wont be popular, too high maintaince cost
0:18
whats this
This in my recommandations and seems I'm the first one since a long time !
Expected Bad Apple to start playing
Weren't flip displays around in the 70s
Chewbacca SaurusRex nothing to this scale though but yes they did
i bet bad apple could be played on this 👀
It's like a black and white OLED display 😅
What is this?
Think of it as a mechanical display where the pixel is either black or white and its state is mechanically controlled hence the noise when the image is moving or refreshing.
Its funny how Physical noise from the tiles and Analog Noise from an Old TV sound almost the same lol
Except that "physical," "analog," "noise," and "old" aren't brand names; and that all actual sound that we hear is physical, and thus analog, anyway. And that a TV doesn't have to be old for you to hear this sort of sound on it.
What is the point
I love the sound xD
you could make frequencies with this to trick the ear into hearing things...
